Tire

Abstract

A tire includes a pair of bead cores, a carcass layer extending between the bead cores, and a belt layer disposed on an outer side of the carcass layer in a radial direction. A tire outer diameter OD (mm) is in a range 200≤OD≤660. A total tire width SW (mm) is in a range 100≤SW≤400. The belt layer includes a pair of cross belts formed of a wide cross belt and a narrow cross belt. A distance Tce (mm) from a tread profile to an outer circumferential surface of the wide cross belt in a tire equatorial plane CL has a relationship 0.008≤Tce/OD≤0.130 with respect to the tire outer diameter OD (mm).
